Pontiac GTO. Couple of reasons. RWD, very powerful (LS2 is the most power for the money in fact), very comfortable interior, seats 4, the sound the exhaust makes is pure sex, the looks are simple yet very pleasing to the eye. I am currently infatuated with this car. I want to buy one for daily driving. I am just waiting for Carmax to throw one into the inventory, so I can get my hands on it. The only downfall I see about the car is since it's a V8 it sucks up some gas, but it's not that bad. In fact, it's almost like a 350Z, just a little worse.
The last car I would get on that list is an RX-8. Slowest car of the bunch, torqueless (which is kind of boring in everyday traffic), and when you get down to it, it's a 4 door.
